For your favorite procrastinator, give them their own "Round Tuit" whenever they say "I'll do it when I get around to it", or even if they have said this any time in the past. I am not the original creator of the Round Tuit. The Round Tuit has been around for many years as a gag gift and is certainly in the public domain by now. Most are wooden discs or coins, but mine is a 3D model. The big one is 100mm diameter and a little thinner, the small one is 50mm diameter and a little thicker. Scale them however it suits you. Both of them print easily and require no support. I printed directly without a raft, etc. for adhesion.
